The principle of Combined Antennas is to integrate multiple antennas with different functions onto a common physical platform, enabling the coexistence and collaboration of various wireless communication systems. Through careful design and optimization, Combined Antennas can receive and transmit multiple wireless signals within a limited space while minimizing mutual interference between them. The principle of Combined Antennas mainly involves the following aspects:
Based on the operating frequency bands, polarization methods, beamwidths, and other characteristics of each communication system, the appropriate types and quantities of antennas are selected and placed on the common physical platform. This requires consideration of coupling effects and interference issues between different antennas.
For multiple simultaneous wireless signals, circuits or algorithms are used to separate them and send them to the respective antennas for transmission or reception. For transmitting signals, multiple signals need to be synthesized or combined to enhance the overall transmission performance.
The working frequency bands of Combined Antennas may overlap or be adjacent, requiring effective spectrum management to prevent interference between communication systems. This could involve techniques such as frequency division multiplexing, time division multiplexing, and code division multiplexing.
By adjusting the antenna gain and directionality, the signal reception and transmission performance can be further optimized. This may involve modifications to the antenna structure, size, and materials.
In Combined Antennas, the electromagnetic fields between different antennas may interfere with each other, causing performance degradation or increased interference. EMC design is necessary to reduce coupling effects and interference issues between antennas.
In summary, the principle of Combined Antennas is to achieve the coexistence and collaboration of various wireless communication systems through comprehensive design and optimization, in order to meet the diverse and high-performance demands of modern wireless communication systems.
Combined Antennas support multiple frequency bands and can switch between different bands to accommodate different communication networks.
Combined Antennas support various polarization methods, including vertical polarization, horizontal polarization, left-hand circular polarization, and right-hand circular polarization, enabling them to adapt to different signal propagation environments.
Combined Antennas can simultaneously receive and transmit signals in different directions, improving the coverage range of communication signals.
Combined Antennas should be installed at a high location to avoid obstructions and interference. If specific areas need to be covered, they should be installed at the center of the target area.
Combined Antennas can adjust the direction of signal reception and transmission. Adjustments can be made according to the actual situation to improve signal coverage.
Combined Antennas can switch between different frequency bands, allowing the selection of the optimal frequency band based on the actual situation to improve signal quality and coverage.
Combined Antennas use antenna array technology to simultaneously receive and transmit multiple signals, thereby enhancing the signal coverage range.
Combined Antennas incorporate signal processing technology to process and optimize the signals, improving the quality and coverage of the communication signals.
In conclusion, Combined Antennas are multi-functional antennas that support multiple frequency bands, polarizations, and directions simultaneously, improving both the quality and coverage of communication signals. The use of Combined Antennas can address communication dead zones and enhance the stability and reliability of communication networks.
